FIELD OF THE INVENTION

[0001] The present invention relates to a dental floss dispenser, and more particular to a floss dispenser integrating advantages of conventional toothpick as well as floss box. The floss dispenser includes a bracket on which the floss is robustly supported for facilitating easy and smooth cleaning process between the teeth. In addition, the floss can be replaced anytime according to the necessity. The floss dispenser features simple configuration while the length of floss for flossing can be economically used.

DESCRIPTION OF THE PRIOR ART

[0002] Conventionally, dental floss is used to remove food debris and dental plaque between teeth by flossing plaque out of the space between two teeth, extending the floss to gingival sulcus, and then sweeping along teeth surface thereby preventing any bacteria growing there. There are many commercial available floss in the form of floss box and toothpick for the dental cleaning purpose.

[0003] In use, a certain length of floss is cut from the floss box, and tensioned between fingers from both hands. Then the floss cuts into the space between two adjacent teeth, and with the upward and downward movement of the floss therealong, the food debris can be kicking off therefrom.

[0004] However, this conventional application has the following disadvantages. Firstly, hands carry bacteria and bring into the mouth during the cleaning process. Secondly, the length of the floss is hard to control. If it is too short, then it imposes a difficulty in cleaning, if it is too long, then it is surely a waste. Even there are toothpicks bonded with floss holder, this disposable toothpick is really not healthy to our environment from a pollution viewpoint.

SUMMARY OF THE INVENTION

[0005] It is an object of this invention to provide a floss dispenser in which the length of the floss can be accurately controlled, while the tension of the floss is also properly controlled so as to provide a user-friendly application.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENT

[0025] Referring to FIG. 1, an exploded view of a floss dispenser in according to the present invention. The floss dispenser generally includes a housing 1 on which a detachable cover 2 is attached. The floss dispenser further includes a floss bobbin 3, a ratchet 4 and stopper 5, a tensioner 6 and a cutter 7.

[0026] The housing 1 defines a receiving chamber 11 in which a bobbin shaft 12 is mounted. The receiving chamber 11 further defines a feeding hole 1A and a side feeding hole 1B. The housing 1 further includes a cutter cell 13 adjacent to the receiving chamber 11 in a middle portion thereof. A cutting knife 7 is assembled into the cutter cell 13 by means of a screw 72 through a hole 71 of the cutting knife 7. The housing 1 further includes a ratchet socket 14 in which the ratchet 4 is installed. The ratchet 4 is moveably assembled in the ratchet socket 14 a screw 43 and other assembling kits which will be described in detail later. Adjacent to the ratchet socket 14, a stopper cell 16 in communicating with the ratchet socket 14 is provided. The stopper 5 is mounted therein by means of a screw 52 through a mount 51 thereof. The stopper 5 extends into teeth of the ratchet 4 such that the ratchet 4 can rotate along clockwise.

[0027] Adjacent to the ratchet socket 14, a tensioner bracket 17 is provided. The tensioner bracket 17 defines a feeding hole 1C and a shaft hole 17A for assembling the tensioner 6 therein. The tensioner 6 is mounted into the tensioner bracket 17 by means of a rivet 63. Finally, at the opposite end of the receiving chamber 11, a floss fork 10 is provided. The floss fork 10 defines a guiding slot 10A along its outer surface, and a pair of notches 10B at ends of the fork for supporting the floss therebetween. A post 10C is provided adjacent to an inner beam of the fork 10.

[0028] Referring to FIG. 2, after the floss bobbin 3 is disposed within the receiving chamber 11, the cover 2 is attached so as to enclose the bobbin 3 therein. As shown in FIG. 1, a detachable threaded 31 is provided for inserting into the feeding hole 1A. The threader 31 includes a passage 31A in which the floss extends therethrough.

[0029] As mentioned above, the ratchet 4 is assembled into the ratchet socket 14 by means of the assembling kit which configured by slotted shaft 41 and a shaft 42. A rubber member 41B is arranged within the slotted shaft 41. By this arrangement, the ratchet 4 can be assembled into a supporting hole 15 of the ratchet socket 14 by means of the screw 43.

[0030] Referring now to FIGS. 3, 4 and 5, a floss route along the dispenser are shown in details. After the floss bobbin 3 is rotationally assembled into the receiving chamber 11. The floss is firstly passing through the passage 31A of the threader 31. Then the floss passes further through the side feeding hole 1B, the feeding hole 1C of the tensioner bracket 17 and out from a passage 62 of the tensioner 6.

[0031] Firstly, a threading device 8 is used to move the floss 3A through the passage 31A of the threader 31. Then the floss 3A is routed through the feeding hole 1 and comes out therefrom to the side of the housing 1. The floss 3A is further threading through the side feeding hole 1B and through the feeding hole 1C of the tensioner bracket 17, such as shown in FIGS. 4A and 4B. Then the tensioner 6 is slightly moved such that the floss 3A can passes through the passage 62 of the tensioner 6. By this arrangement, the tensioner 6 applies a certain tension to the floss 3A.

[0032] Then, the floss 3A routes through the guiding slot 10A of the floss fork 10, such as shown in FIGS. 7 and 7A. The floss 3A then routes along the notches 10B of the fork, and finally anchored at the post 10C. The floss 3A further routes to the slotted shaft 41A of the ratchet 4. As the slotted shaft 41A is inserted with a rubber 41B, the floss 3A is securely held therein. As a result, the floss 3A completes it routing and holds with proper tension.

[0033] When the floss 3A completes its routes and a user would like to use it to floss, the user may slightly press on the tensioner 6 such that the floss 3A is tensioned. Then the user may rotate the ratchet 4 so as to further tension the floss 3A by the arrangement between the ratchet 4 and the stopper 5. Finally, the user can use the floss 3A spanning between the floss fork 10 for flossing. Specially, the tension of the floss 3C can be adjusted anytime by the ratchet 4.

[0034] After a section of floss 3A is used, the used floss 3A can be easily replaced such as shown in FIGS. 9 and 9A. The floss 3A braced between the fork 10 can be easily released from the notches 10B by a further push back of the tensioner 6 so as to release the tension applied to the floss 3A. As a result, the floss 3A can be easily released from the notches 10B. Then the used floss 3A can be cut off by the knife 7, such as shown in FIG. 10. While a new section of floss 3A can be re-routed to the fork 10 according to the procedures described above. After the floss bobbin 3 is exhausted, a new floss bobbin 3 can be refilled and the user may start a cycle of flossing.

[0035] The floss dispenser made according to the present invention can be featured with at least the following advantages.

[0036] 1. The floss dispenser made in accordance with the present invention features the advantages from both the floss box and the toothpick with floss holder. The user can easily to use it to floss. In addition, the floss can be easily replaced while the floss can be economically controlled.

[0037] 2. The floss dispenser made in accordance with the present invention further features a simplified configuration readily for handling. By the provision of the ratchet and tensioner, the tension of the floss can be accurately controlled thereby prevent the break of the floss during the flossing.

[0038] From the above description, it can be easily appreciated that the tension of the floss is controlled by both the ratchet after the floss routes through the post, and by the tensioner right before the floss reach the floss fork. By this two stage controlling of the floss, especially the tensioner provides a dynamic control of the tension of the floss. As such, the user may easily perform the flossing process.

[0039] It should be note that the specification relating to the above embodiment should be construed as exemplary rather than as limitation of the present invention, with many variations and modifications being readily attainable by a person of skill in the art without departing from the spirit or scope thereof as defined by the appended claims and their legal equivalents.
